Method for Executing a Binary Code of a Function Secured by a Microprocessor

2. The method according to claim 1, wherein, in the step a), in the machine code provided, each data line is the first line of each basic block following the first preceding basic block, said data line, contrary to an instruction line, not coding any opcode of an instruction that is executable by the microprocessor.

3. The method according to claim 1, wherein, in the step b), the construction of the initialization vector from the content of the data line, comprises the decryption of a cryptogram ivlsbi* contained in said data line to obtain a first value, then the use of said first value to construct the initialization vector.

8. The method according to claim 1, wherein the content of the destination register is unknown at the time when the binary code is generated by a compiler.

11. The electronic device according to claim 10, wherein the microprocessor further includes a hardware securing module, wherein the hardware securing module is configured to construct the initialization vector from the content of the data line associated with the address obtained from the content of the destination register.
